Some products have reinforced facing to make them sturdier.Click to see full answer. Hereof, what is the R value for Styrofoam? 5.0 per inch is white Styrofoam good for insulation? The polystyrene foam Styrofoam is made of trapped air bubbles that prevent heat energy from flowing through it. This prevents heat loss, making Styrofoam an excellent insulator. In respect to this, what is the R value of 1.5 Styrofoam? Easily recognized by its blue, green, or pink color, XPS falls in the middle of the three types of rigid-foam insulation in both cost and R-value (about R-5 per inch). XPS comes unfaced or with a number of different plastic facings. Unfaced 1-in. -thick XPS has a perm rating of around 1, making it semipermeable.What is the R value of silverboard?
